Device Not showing GCM messages when the application is off

Questions & Answers
1

I saw some threads asking about this, but no answers…
I’m using the GCM plugin to receive push notification from the GCM. I’m sending the notification using the GCM REST api. It works. the GCM respondes correctly, and when i’m in the app, i receive the message and can see it’s data.
But i wanna receive a notification when the app is shut down. The logcat shows that the message arrives, but then i get this line:
“Native libraries not loaded - dropping message for GCMReceiver.OnMessage”

What does it mean? What am i missing? i don’t even know if it’s the manifest, or something inside unity or my code.
Please help

[SOLVED] !!!
Well, that was easy. It has nothing to do with “Native libraries” or anything.
The JSON of the message itself, must contain those three fields:

"data" : {
      "ticker": "ticker text",
      "content_text": "content text",
      "content_title": "title text"
    }

i’m still just making my first steps towards actually using this in the project, but i think i can work with this.
Since there are quite a few followers to this question, i thought i’ll post the answer right away
